Hey everyone,
I’m hoping someone here can help me figure out what’s going on. Over the past few days, I’ve noticed a sudden swarm of house flies inside my home — literally out of nowhere. I’ve been keeping the place clean, trash is taken out regularly, and all windows have screens.
What could be causing this? And more importantly, what’s the fastest way to get rid of them before it gets worse?
@HomeFixer77 That happened to me last summer. I found out the flies were coming from an old mop bucket that had a bit of dirty water left in it. Once I dumped it and cleaned the area, they disappeared in a day.
Check your window screens closely, even a small tear can let them in. I had a few getting in through a gap near my AC vent, and sealing it made a big difference.
Mine started from the compost bin under the sink. Everything looked fine from the outside, but the liner had a small leak. Once I scrubbed it out and replaced the bag, the flies were gone almost immediately.
Sometimes they come from dead insects or tiny rodents in the walls or attic. Not pleasant, but worth checking if the smell seems off. Once the source is gone, the flies stop showing up.
If you have drains that don’t get used often, pour some boiling water or baking soda mix down there. Standing moisture can become a fly nursery fast.
I had a sudden wave of flies and realized it started after a heavy rain. They were sneaking in from the garage through the weather stripping. Sealing that gap stopped it for good.
Honestly, the fastest fix for me was just finding the source and improving airflow. Once I got rid of whatever they were feeding on and kept windows open for a bit, they vanished in two days.
If you’ve got pets, check near their food bowls or litter boxes. Even a few crumbs or leftover moisture can attract flies fast.
Keeping lights off in certain rooms during the day helped me a bit too. Flies tend to gather where it’s warm and bright, so that trick can reduce their numbers until you find the source.
They usually don’t last long once you remove the breeding spot. Stay consistent with cleaning drains, bins, and food areas, and you’ll break their cycle pretty fast.
